STEPHEN S. NEWTON, OF BINGHAMTON, NEW YORK.

BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 251,063, dated December 20, 1881.

Application tiled August 15, 1879.

To all 'whom it may concern:

Be it known that I, STEPHEN S. NEWTON, of Binghamton, in the county of Broome and State of New York, have invented certain new and useful Improvements in Bottle-Stoppers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part ot' this specification.

Figures 1 and 2 are vertical sections of my Stoppers.

A is the bottle, and A is the neck thereof. B is an annulus, of cork or other suitable material, fitting closely within the neck A'. B D is the cork-tube. O is a flange projectinghorizoutally from the central part ot' the cork-tube. The cork-tube is constructed with a central opening extending from its lower end to a point near its upper end, and of nearly uniform diameter throughout, except nearits upper end, where it is contracted, the walls of the corktube being correspondingly reduced, and terminating in an upwardly-projecting head, d'.

d d represent lateral openings or ports formed in the reduced part of the cork-tube B. The outside of the upper end, D, of the tube is screw-threaded, and is of uniform diameter below the head d', by preference.

E is an internally-screw-threaded cap, provided at its upper end with a discharge-port, e, the inner surface of this end of the tube constituting a valve-seat, conforming in shape to the upper end of the head d', which closes the port e when the cap is screwed down, as shown in the drawings, and thereby prevents the discharge of the contents of the bottle; but, as will be readily understood, when the cap E is screwed up the port e is opened to permit the contents ot' the bottle to pass out freely.

In Fig. 1 I employ a narrow ange, c, projecting upwardly from the horizontal tiange C, within which the lower end of the cap E enters for the purpose of hiding the screw-thread upon the tube B D, which would otherwise be exposed when the cap E is screwed up.

In Fig. 2, C is a ange rising from ange O, and having at its upper edge an inwardly- `turned lip, c', adapted to engage with an outthe cap E,to prevent the accidental removal of said cap.

l am aware that a patent granted N. D. Whitin, April 29, 1842, shows a cork-tube constructed with a screw-thread at its upper end, in combination with an internally-screwthreaded cylinder or cap having a central dischanging-port, the cork-tube having vertical ports in its upper end, which are closed by the screw-threaded cylinder orcap; butin Whitins stopper the opening through the cork-tube is expanded at the upper'end, thus necessitating the employment of a core with a bulb or head at its upper end in casting the cork-tube, whereas in my construction, by the use of the contracted neck and lateral ports d and head 1l/,I am enabled to construct my cork-tube core without the bulb or head at its upper end, which facilitates manufacturing the stopper cheaply. Again, in Whitins stopper the employment of the enlarged chamber at the upper end of the cork-tube necessitates the use of a discharging tube or cap'having a much greater diameter relative to the diameter of the tube where it passes through the cork; and 1 have found that my construction facilitates the discharge from the bottle of such material as powder, because I can make the tube of comparatively large internal diameter, with a row of ports equal in area to the area of the tube in cross-section, the contents of the bottle being forced through the ports by the pressure of a comparatively deep body of material directly on each port. In my stopper the arrangementot the lateral ports of the cork-tube in the reduced portion ot' the tube permits liquid to ow from the bottle into the cavity which surrounds the upper end of the corktube, and as this liquid is liable to pass down the screw-threads I have found it desirable to employ aflange, G, projecting horizontally from the cork-tube at such point that the lower end of the cap will abut against it (the iiange) to prevent leakage at this point.

What I claim is- 1. In a bottle-stopper, the cork-tube B. D, provided with an internal opening of substantially uniform diameter throughout and of reupper end, in combination with an internallyscrewthreaded cap provided with a discharge- IOO 3. In a bottle-stopper, the combination oi 15 the flange C, the vertical flange c, the screwthreaded part D of the discharging-tube, and the internally-screW-threaded cap E., substantially as set* forth.

In testimony that I claim the foregoing as zo my own I afx my sgnaturein presence ot two witnesses.
